Which way round
Clockwise: Easy first 3.0 km, no steep climbing, comes down 17% for 250 m early on.
Anticlockwise: Easy first 4.9 km, climbs 17% for 250 m near the end, no steep descents.
Better anticlockwise: you climb the steeper side (0.3 km at 10%+, 0.3 km of it 15%+) and come down no steep ground. Steep descents are where people slip, and they're harder on knees late in a walk.
Main climb: km 4.9–6.3, from 103 m to 206 m.
